The IBEX Award-winning I-4 V MAX SHO® 150 was the first of its kind, inspiring the VF175 and VF115, delivering exhilarating top speed with a 7.7-second hole shot and signature V MAX SHO performance through its innovative design that maximizes combustion efficiency for clean, quiet power that no two-stroke can match. Featuring a 2.8-liter high-output four-cylinder engine with 480 lbs. dry weight and available in 20-inch and 25-inch shaft options, the V MAX SHO® 175 and 150 utilize Variable Camshaft Timing to optimize intake camshaft angle for increased midrange power and throttle response, while Precision Multi-Point Electronic Fuel Injection combined with a long-track intake system delivers up to 40% better fuel efficiency than traditional carbureted two-strokes. An advanced Engine Control Module uses data from multiple sensors to make instant adjustments for optimum performance, while the Cowling Drain System and Air Intake Labyrinth System trap and drain water during normal operation, and wet sump pump lubrication with pressurized oil delivery ensures superior engine protection. The comprehensive Engine Warning System provides overheat protection, low-oil-pressure warning with automatic RPM reduction to 2000, over-rev protection, water-in-fuel detection, start-in-gear protection, and shift-in prevention at open throttle, while Phaze Five™ electro-deposited anti-corrosive paint combined with proprietary YDC-30 alloy creates a tough five-layer barrier against corrosion. The space-saving in-line four-stroke design eliminates the need for an external oil tank, providing more storage room for tackle and gear, while the powerful alternator delivers 50 amps of charging capacity for the 175 and 150 models (35 amps for the 115 and 90) to support battery charging and on-board electronics, with easy mechanical controls compatible with most bass, bay, and flats boats and analog, 6Y5 digital, or Command Link® gauges, including Command Link® compatibility with Variable Trolling features.
WHAT'S INCLUDED
Additional Features
The I-4 V MAX SHO® 150 features an inline 4-cylinder, 2.8L displacement engine with 96 x 96.2mm bore and stroke, delivering 150 hp at 5500 rpm with a 5000-6000 rpm full throttle range and 10.3:1 compression ratio, utilizing EFI fuel induction with recommended 89 octane fuel and Yamalube® 4M oil (4.5L/4.3L capacity) filtered through a Yamaha 10-micron fuel/water separator supporting up to 10% ethanol blend. Weighing 489 lbs dry with a 25-inch shaft length, this 3-Star CARB-rated outboard incorporates TCI microcomputer ignition with LFR6A-11 spark plugs, electric starting, wet sump lubrication, thermostatic cooling control, and through-propeller exhaust, while generating 50 amps of alternator output at wide-open throttle. The motor offers a 2.00:1 gear ratio with forward, neutral, and reverse shifting, 70° of tilt and -4° through +16° of trim, 32° maximum steering angle from center in either direction, and is backed by a Limited 3-Year Pleasure, 3-Year Government, or 1-Year Commercial warranty.
